To all whom it may concern;

Be it known that I, Gear DALZN, a subject of the King of Swederifresidin at Stadsgarden 18, Stockholm, in the King cm of Sweden, have invented a certain new and useful Improvement in Storing Mass for Acetylene Gas, of which the following is a specification.

This invention'relates to the storage of acetylene gas dissolved in acetone.

It has already been proposed to use a porous absorbent mass for storing compressed gaseous acetylene for the purpose of preventing the gas exploding. he absorbent mass is cosed of silicious earth,

charcoal and lime cement e a er emg employed as an adhesive or binding substance, for which it is eminently suitable.

If the acetylene gas to be stored be dissolved in acetone however, as is now a usual form in which acetylene gas is stored, it has free oxids or lime or cement cannot be used partly because the capacity of the acetone to dissolve acetylene gas is diminished when in contact with such substances, and partly because the acetone chemically Qfi'ects such substances. It has therefore been a practice to employ cla r a mixture of zinc oxid, and zinc chlon instead of lime or cement when s ormg acetylene dissolved in acetone.

The present opinion that lime is not capable of being employed when storing acetylene gas dissolved in acetone seems to be right. But experiments made by the applicant show nevertheless that cement can with advantage be used for the pur that it does not contain an ree oxi-d such as for instance Tree alkaline earths. The said experiments Have shownv that it is the free alkaline earths which affeet the acetone and diminish its capacity of dissolving the acetylene gas so that lime alone is not capable of being employed under any circumstances for the said purpose.

The present invention has for o ject to provide a porous mass suitable for storing acetylene dissolved in acetone, emplo 'ng cement'as an adhesive or binding su stance.

ose, provided Patented May 18, 1915.

Examim ment employed is h draulic cement and such that, when chemlcally analyzed, it is found not to contain any, or any appreciable amounts, of free oxids such as for instance free alkaline earths; or the cement employed has added to it substances which have the ca acit of formin salts or double 'sa'lts with an Tree oxids such asalkalm'e earths con aine 1n e cement. As examples of such substances zinc chlorid, hydrous silicic acid ozzuolanmn e be mentioned.

The orous mass also contains as usual charcoa and siliciqllfsgerthto which, if desued, in known manner may be added fibers of asbestos or the mass EreaEng when dried.

I claim 1. A porous mass for storing acetylene dissolved in acetone, containing a hydraulic cement which does not contain free oxids.

2.'A porous mass for storing acetylene like for preventing the emay' dissolved in acetone containing a hydraulic cement in which the otherwise free oxids are bound by substances adapted to form compounds with the said oxids.

3. A porous 'mass for storing acetylene dissolved in acetone, containing hydraulic cement in which the otherwise free oxids are compounded with pozzuolanic material.

4. A porous mass for storing explosive gas dissolved in acetone, comprising charcoal, silicious earth and hydrau1ic,cement which does not contain free oxids.

5. A porous mass for storing explosive gas dissolved in acetone,

silicious earth, fibers of elastic material and comprising charcoal,-

hydraulic cement which does not contain free oxids. v

6; A porous mass for storing explosive gas dissolved in acetone, comprising charcoal, silicious earth, fibers of elastic material, hydraulic cement and with free oxids.

In testimon whereof I aflix my signature in presence 0 two witnesses.
